Thats kinda the point. The mother goddess isnt real she is an usurper from the abyss like the little mermaid who comes from the waters, and makes a deal with the devil to ascend as a star (Stella Maris).
She made a pact with devils to empower and enrich herself further and amass a huge powerful following without any actual talent to validate it. Between the Swifties, as well as ruining the career of people who have rubbed her wrong (Ye, Katy Perry), and who knows who else she has trampled over.
Because her power is stolen, it means that her sacrifice would return what was stolen to the rightful victims.
